Upside-Down Sausage and Mushroom Pizza

Adapted from a recipe courtesy Robin Miller 2007

Ingredients:

2 teaspoon canola oil
1 pound sausage, casing removed (I used half hot and half mild
1 cup onion, sliced thinly
8 ounces mushrooms, sliced
2 cups quick tomato sauce (see blog for recipe)
1/2 cup black olives, sliced (I used Trader Joe's canned green olives)
16 ounces mozzarella cheese, shredded (I used Trader Joe's marinated rope mozzarella and thought 8 ounces was plenty)
 2 eggs
1 cup milk
1 tablespoon olive oil
1 cup all-purpose flour
1/2 teaspoon salt
1/4 cup Parmesan, grated

Directions:

Preheat oven to 400 degrees F.

Heat oil in large skillet over medium heat. Add sausage and cook for 3 minutes, or until browned and cooked through, breaking up the meat as it cooks with a wooden spoon. Add onion and mushrooms and cook 2 minutes, until soft. Add tomato sauce, olives and bring to a simmer, about 2 minutes. Remove from heat and transfer sauce to the bottom of a 13 by 9-inch baking dish. Top with mozzarella cheese.

In a medium bowl, whisk together eggs, milk and oil until blended. Whisk in flour and salt until well blended. Pour mixture over sauce in pan. Sprinkle with Parmesan. Bake 25 minutes, or until golden brown. Let stand for 5 minutes before slicing and serving.
